Personally, I am not outraged.
These were stones that were worn out and replaced by new stones. Once they are removed and replaced at the cemetery, to me, they are just old stones that no longer represent anything. The grave itself is important to me, not the stone that once marked where it is.

Headstones are replaced if they are damaged or if the writing on them becomes illegible, she said. At one time, gravestones were discarded in landfills. The cemetery ended that practice because Washington area residents were plucking the stones and using them for patios, driveways and other home improvement projects. Under the current disposal policy, headstones are to be ground up so the names cannot be recognized and then recycled.
I would not have a problem if one day my worn out and replaced headstone was used by someone for a useful purpose.
Now they are ground up and possibly turned into tiles for a bathroom floor, who knows.

I would like to see them offered to next-of-kin before being destroyed.

Stealing or vandalizing stones from atop graves is a different matter. Shoot the bastards.

Interesting video about where military headstones come from:
